Charles,
Go ahead and list them. I am always looking to learn or perhaps could be future purchases.
Thanks.

Any options for low power class A amps?
Okay, I do most of my music listening at work because of time constraints. I have a nice desk system that includes some 4" Fostex full range speakers, an Olasonic dac, an Olasonic cd transport, and an integrated Olasonic amp/dac. I have nothing but good things to say for Olasonic however I would like to add better amplification. I am looking for a small solid state amplifier that is pure class A in the 5 to 10 watts range. The only ones that I have found have a higher power rating and are huge or are A/B amps that are biased slightly higher. I don't know if anyone makes class A amps in this power rating. If you know of any I would greatly appreciate your help. I have tried headphone amps that are pure class A that results in an improvement but the impact is not there due to power and impedance matching of speakers in comparison to headphones. The Fostex drivers I am using are 16 ohms btw. Thanks.

Hi Audioman, One in particular is the Coincident Dynamo MK II (current version). Substantial upgrades from the original (which was already very good). A beautiful match with efficient speakers per experienced listeners I trust. Beefed up power supply, higher quality output transformer, crucial areas for a tube power amplifier. Pure class A single ended el 34, 8 watts. Charles, |
Have you considered a (low cost > sub $500) Jolida 302? I
know that your first post pointed out that you were looking for a Transistor vs
Tube amp but, A lot of the “full range” speaker users gravitate towards smaller
“tube” amps (you will get a better mellow but, robust) sound: Here is my 50Wpc
Jolida 302 running my (rather inefficient) 82Db Infinity Renaissance 80's w/
some major authority: https://youtu.be/Pp2DuUza3Ys
(Please listen on a system that will allow for the full range sound to be reproduced > not iPods, trust me you will hear & feel the difference) One of these "small" Jolida amps (their simple and reliable) would run your whole (Fostex) system w/ a lot of "punch" and clear sound!?! I have a pair of audio research reference 300 mono blocks running in my "main" system but, I swear; this "little" Jolida (tucked in my guest room) sounds "damn" near as "clean & clear" as a system that cost 40x as much! You might want to take a look at them as a "cost saving" venture that will "future" proof your whole system? They are not too small and quite heavy (50Lbs) but, leave a rather small “foot print”; the sound is fantastic! -Davis |
Amp camp amp ACA from Nelson pass, as diy kit + 2nd hand market http://diyaudiostore.com/products/amp-camp-amp-kit Valvet e1r also look at TPA3116 or 3118 chip amps - fleawatt is a good source http://fleawatt.blogspot.com/ If if you have the money go for the microzotl2.0 deluxe |
Audioman ; Assuming your reason for asking about Class A is to get clear,clean sound with great low level resolution and good soundstaging , I suggest you look into the Class D Audio SDS power amps . Most Class A run hot , either solid state or tubes, and these do not. They are also a small form factor and very affordable , IMO . I tried one after my 2A3 SET amps and found the sound nearly identical , except better in all regards and also with NO hum or noticeable distortion . None are as low-powered as you mentioned , but they are very energy efficient and you can use as much or little of the available power as needed by turning the volume control of your control amp . This is their lowest powered amp in their best series ; http://www.classdaudio.com/sds-series-amplifiers/sds-120c-class-d-audio-power-amplifier/ Read their " Testimomials " |
